I don’t think the “aside from the internet, nothing much”. Firstly comuter and internet tech have been fairly revolutionary across substantial chunks of industry and our daily lives. This is the “a smartphone is only 1 device so doesn’t count as much progress” thinking. Without looking at the great pile of abacuses and slide rules and globes and calculators and alarm clocks and puzzle toys and landline phones and cameras and cassette tapes and … that it replaced and improved on.
Secondly, there are loads of random techs that were invented recently, solarPV, LED’s. Mrna Vaccines. Electric (self driving?) cars.
And finally, a substantial part of progress is the loads of tiny changes that make things cheaper and better. If you don’t include things like 3d-printers and drones that haven’t really gotten good yet, then of course you will see less inventions recently. The first fridges were expensive and not that good either.
Elon musk is very good at making himself the center of as many conversations about technology as possible.
He should not be taken as a source of information of any reliability.
Living on mars with tech not too far beyond current tech is like living in antarctica today. It’s possible, but it isn’t clear why you would want to. A few researchers on a base, not much else.
Think ISS but with red dust out the windows.
At some point, which might be soon or not so soon, tech is advanced enough that it becomes easy to get to mars. But at that point, traditional biological humans on mars might be stupid, compared to say self replicating robots containing computers running uploaded human minds in the asteroid belt.
A mars base is cool scifi. But it might turn into the largest white elephant in history. It doesn’t solve any obvious practical purpose in increasing human wellbeing or industrial capability.
Sure, at some point you are disassembling all the planets to build a dyson sphere. But before that, a mars landing doesn’t actually need to mean any real progress.
